Underwriting Ratios

Net income for the three and six months ended June 30, 2025 increased primarily due to a higher underwriting gain, higher net investment income, and for the three month period, lower net realized losses. For further discussion of investment results, see MD&A - Investment Results.

Underwriting Gain

Underwriting gain for the three and six months ended June 30, 2025 increased due to the effect of earned premium growth, higher favorable prior accident year development, and for the three month period, lower CAY catastrophe losses. These favorable impacts were partially offset by a higher underlying loss and LAE ratio, and for the six month period, higher CAY catastrophe losses.

Expense ratio for the three and six months ended June 30, 2025 improved modestly as the impact of higher earned premium was partially offset by increased technology costs, including increased investment.
